I never met a broken TV I didn't like. Come read the blog at https://www.leadedsolder.com and see what old junk computers I'm fixing this week.

That might be helpful actually. I'm currently using a screw jammed in the servo horn until I can work out how I want the action to work...

Oh, the electronics side is easy. I'm having trouble figuring out a linkage that works.

I'm trying to convert a toy RC car into a proportional steering using that exact same servo at the moment. It's been challenging!

Every time it comes up I just gotta remind people that it's extremely expensive to license filming in Shibuya, which the team making this game couldn't afford, so they filmed this game by stealing shots and running from the cops.

There's a table somewhere for "normal" resistance per length of spark plug wire. I've used it all of once and then found there was a big hole in the side of the questionable wire while going to ohm it out.

Successfully opened SSH connection to my Linux box from my Panasonic FS-A1 #MSX via #FujiNet. This means network functions are working as expected.

Now our apps can start to be ported.

What if the Apple ][ had run on Field-Sequential? One thing I remain fascinated by is the field-sequential color system. Essentially, unlike composite video, which sacrifices color depth in space, field sequ...

New blog post! A what-if scenario where we try to see how a home computer designer might've dealt with the field-sequential color television, had the Korean War not stopped that standards' rollout. Enjoy! nicole.express/2026/the-app...

What are you doing for text compression?

I can't play it well, but I love everything Artdink makes. I'm not sure what else they did for FMT.

I've always wanted an A/ROSE card just for general purpose computing and playing with. It's such an interesting concept

I just got mine working finally. No keyboard or mouse, but I'll get there. It's a very neat machine with lots of secrets yet to uncover.

In your professional opinion, is it museum grade?

We had one but the rest of them were almost all Apple II.

if you're buying numarathon it's incredibly important that you fully internalize the timeline you can't even leave the tutorial if you don't understand this

Thanks! Tandy used the name fairly irresponsibly - it covers everything from the 6809-based CoCo to the 68000-based XENIX machines, with lots of toy computers and glorified calculators in between. I'm sure it caused lots of headaches at the stores when people were trying to get software...

Untrashing a TRS-80 This Model 1 TRS-80 has been through a lot before it was rescued out of an e-waste dumpster by my friend. With some patient work, I should be able to turn it back into a computer. But how bad will thi...

New blog post! This TRS-80 Model 1 was found in the bottom of a trash bin, smashed to bits by heavy printers and cash registers above it. Will it ever run again?

I don't know anything about telecom, but that does seem odd to me too. Perhaps it just doesn't work :)

I opened the flap, if that counts. I also wonder how often it gets used.

This looks like a really fun card (and machine.) I do have a Macsbug book here but I don't think it ever went into video card stuff.

If memory serves you can also do Macsbug over serial in a pinch. What's the card?

Thanks! It was suggested that the epoxy is definitely for temperature compensation but it was the first time I'd ever seen something like it in a power supply. I gotta build an analogue synth so I can learn more about fun analogue stuff!

If a little cap makes the power filter good, then big cap make power filter even gooder!
